The construction ofthe machine, particularly the wire coiling and wire-interweaving mechanism, can best be understood if the type of nettin made by the machine and the manner o interweavin the wire sections of that netting, is rst explained; therefore reference is made first to Fig. 26, showing a portion of 'the netting and to 30 Figs. 22-25 inclusive, illustrating lschematically the manner of interweaving the wire `sections which make up the netting. As shown particularly in Fig. 26 the netting consists of a plurality of zigzag wire sections A, B, C, etc., extending transversely of the netrting and clenched at their ends to selvage wires Z. In this netting there are no separate warp and woof wires (except as possibly the selvage wires Z may be understood to be warp wires; in which case the transverse wires A, B, C etc., may be considered woof wires). But the wire sections A, B and C are intercoiled or interwoven as illustrated in Fig. 26, each with the two adjacent wires, in such manner as to avoidl all occasion for separate warp and woof wires. Eachl of the sections A, B, C etc., consists of a attened helix Aso flattened (as shown particularly in Fig. 25) as to lie very nearly in The-convolutions of each wire section are staggered with respect to the convolutions of the two adjacent wire secl tions, but only aportion of a phase (half a phase in the construction shown). 'The wire coiling devices employed are themselves of well known construction (except in the respects hereinafter noted) comprising (see Figs. 22-25 inclusive, also Figs. 6 and 7) a fiat coiling blade 13 surrounded,

" through a portion of its length, by a coiling die 12 which has the form of a hollow helical ribbon, the adjacent turns of which are separated slightly so as to provide alielicalslot 12a (Figs. 7 and 2,5) through which the wire'to be coiled may) travel. This coiling device windsthe wire as a flattened helix closely enveloping the coiling blade 13 (asf shown particularly in Fig. 6, wherein two separate and distinct coiling bladesv13 are shown, each surrounded by a coiling die 12` 70 and each closely enveloped by a wiresection A). gIn the operation ofthe machine, the first wiresection (A, for example) is woundy up by one of these coiling devices 12-13,

as indicated in Fig. 22. Such 'section is' out 75 olf (by means hereinafter described) and is held temporarilyl in the position shown, while the next wire section B, is wound and interwoven or intercoiled with the section A, As previously explained, with reference t Fig. 26, this next wire section, B, should have its convolutions stag ered, with. re,` spect to the convolutions o the section A, but half a phase. Such staggering might be effected by moving the wire section A lengthwise, half a phase, but this is objec' tionable in that it"- would involve, after the weaving is well started, the shifting back and forth, laterally, of a considerable portion at least, ofthe netting already woven. Therefore, I prefer, instead of shifting the already coiled sections laterally, to shift axially the coiling die 12 to an extent suiiif cient to produce the desired phase-staggering of the successive wire sections." There- 95 fore, as indicated in Fig. 23,'for the coiling of the wire section B (the section following Anext after the section A) the coiling'die 12 is shifted backward `axiallv half a phase; as a result of whichthe sectionvB is staggered withv respect to the section A, but half a phase; and this section B, as it leaves the coiling blade 13, willtwist into engagement with the-coils of section A, as indicated in i Fig. 23. The interwoven section A is then lifted a suitable distance, and, the coiling die 12 being returned to first position, as indicated in Fig. 24, the third wire section C, is formed and caused to engage with the coils of section B. Thev coils of the section C then correspondy exactly with the coils f the section A, but' are staggered half a phase with respect to the coils of section B. The weaving of the netting proceeds in the manner described, alternate sections B, D, 115 etc., and A, C, E etc., being intercoiled or interwoven, and being all of the same length, though each wire section is sta gered with respect to the two adjacent w1re sections, but half aphase. 120 Referring now to *'Figs. 1 and 2,1 designates a bed-plate upon one end of which are mounted uprightstandards 2 which support two reels or spiders '3, for holding wire from' which the coiled Vwire-sections of the ,net-v ting are to be formed; which reels or spiders are loosely mounted upon opposite ends of a shaft 4 having its bearings within the standards 2.

The spiders or reels 3.are in the present instance rovided vwith'suitable armsj to the ends o which are secured anged sleeves 6 by means of suitablebolts7. A number of holes 7a are provided for the bolts 7 ,to permit :ofthejflanged sleeves 6 being set-at ..va

' rious distances from'the hubs so as to vary the capacity of -the reels.

Uponv the bed-plate 1 are also mounted three frame standards 8, 9 and 10, on-top of, which are mounted duplicate wire coiling'z devices 11 (see Figs. 6and7). One wire -coiling device is situated on one side. of the machineand receives wire from the wire-reel on the same side ofthe machine; the other wire coiling device being situated on the other side of the machine and receives wire from the wirev reel on its side of the `machine; all as shown in Figs. l and 2. It lis usually customary to insert suitable wire stretching devices between the reels and the) icoiling devices, but as'these. stretching. de-

vices form'no part of they are' not shown.

The machine shown being'. a double inachine,'to maketwo independent nettings,

the present invention .and the two wire'coiling devices-'11 being alike, only one will be described. 1-

In the present instance the colling device comprises a hollow'die 12 (see Figs. 6 and 7) provided rwith a helical opening 12av which extends from one end of the` die to the other. A soiling blade' 13, one end of which is secured to a shaft 14, (see Figs. 1', 2 and 4) is adapted to ltloosely in said die.. The shaft 14,- to which. said coiling bladeissecured, is journaled in a suitable bracket 15,

and also; upon the. frame standard 8 (see 1 and 4.) Y For suitably-rotating the. coillng blade 13 a gear'16,` secured on the shaft 14,' islarranged tofv engage a gear 17 loosely mounted on themain driving shaftk 18 of the machine. A-su'itable clutch'19' is s provided. for'engaging the gear 17 intermittently to operate the coilingdevi ce, afsuitable friction device'20, adjacent thedriving pulley -21 being providedV for obviating un# due shock in starting the machine. l

The wire A as it comes from the reel is vwoundabout the iiat ceiling blade 13 and is drawn along the spiral openings 12, in

the die 12,'.at the' same time, thereby bending. the'wlre and feeding it l outward, as

the middleportion-of' the screw bein i jourf4 naled' ein. Ia boss secured' to the sl1de23L1 dovetailedgroove 28 ofthe ways 29, suitable vadjustable stops inthe forniof screws '30 being provided for limiting the movement of the-slide. Tothe bottom oftheslide 23 7nis secured a projecting member 31 havingv a longitudinal recess 32, in which is slid-ably mounteda. cross piece 33, through the cen-V ter ofU which is, threaded a screw 34. '1`hcv ends of the'screwl 34 are .loosely mounted inA 75 the projecting member 31, a collarv 35 being\ secured to one end of said screw anda hand wheel 36 secured-'to the other end, which permits of the cross piece 33' being moved back and forth along said recess.

of the projectingmember 31,. both ends of said cross pi `being engaged by the inner- -ends 'of the recessed portions of the fork '37,` the vouter en'd of which is provided with" 85 suitable lugs, towhichonefend of the lever '38, is pivoted at 37a. lThe lever 38 is secured intermediate of vits length to a rock shaft 39,

' to which'isr securedan-arm 40, the lower end o f the lever 38 being provided with a roller 90.

41 which engages the'cam groove Vof the cam 42.

From the above it will be'seenthatwhenthecam -42-fis rotated,' 'in Vthe operation of the machine, the lever 38l will be vibrated 95 back and forth about the 'shaft 39; the lvi-vv brations of the lever beingcontrolled by the. shape of the cam 42, .in which the roller 41, f secured to the, lower end `of the lever 38,

operates. lThe vibrationfof the lever 38 100 vibrates Vthe wire ceiling' device, .through the .-me'sdium'gof thev fork 37, to. which onev endof the lever 38jis pivoted, the otherjend of the fork' 37 engaging the projecting ends of. thecross "piece 33,105

the' position of which is regulated-by means ofthe hand wheel-36 vso as to give'a certain amount of lost motion vin the operation of the leverA 38 to move the wire coiling device.

The position ofl the cross piecef33, in 'Fig. 110

-.7, is such that when the fork. 3 7 is moved tol thel right by the further inovement`-of` the cam 42,.the inner end ofv tl1'e' '1ecessed l portions ofthe fork will notcome in con-' v y tact with theends of the cross piece to move 115 the wire coilng device, until the'forkhas y been moved a slight distance;A Whenthe -lever 38'is forced to the-.left -'on the return movement-, .the inner side of the vfork 3-7 I Q 4'adjacent the pin 37 a' engages the rightlhand 12,0 side, ofthe projectingv member 31after1a certain amount o'f-lost motion is taken up," just as was previously the case when. the wire. coling device was moved to the right.

The wire coilin device 11 is moved' for-125 wardorfbackwar' a distance equal to one -1 half the pitch of thecoils ofthe wire, every time'a new wire section is to beadded'to the i netting.. By referring to Fig. 7, it, will :be l' seen-that'the wire ldevice 11 has been." 1 3()v The ends of i said cross piece 33 extend beyond, the -sidesK vthe wire section marked moved, by the action of the cam 42, toits extreme left-hand position, the coiling device having just been moved from its eX- treme right-hand position in which position having reached the desired length, was cut off, to permit of the neXt wire 'section marked C4 bein vanced into the position shown, wherein its convolutions are staggered with respect to those of section B. rlhe wire coiling device is moved forward as just described to permit of the new length of twisted wire section C, in its forward movement, to intermesh with the previously formed wire section marked B.

When each wire'section A, B, C.,etc., has.

reached the required length, it is cut olf, as

" hereinafter described, and then the coiling -'devi`ce,11, is moved by the action of the cam 42, forward :or backward, vas may be required, a vdistance equal to half the pitch of the convolutions, so that the wire section neXt formed will have its convolutions staggered with respect to the convolutions of the wire section just previously formed. J

In the movement back and forthvof the wire coiling device it is to benoted that the `coiling blade 13 does not move but remains always in the same position. It is also to be noted that the die'12 only moves forward. or backward immediately after the previously formed wiresection has been cut off;

at other times, or 'while the wire section is being formed the die 12 remains stationary.. l

The cam 42, which moves the wire coiling device forward or backward, is secured to a shaft 43 provided with a spiral gear 44, vwhich'meshes with a spiral gear 45 secured to the secondary shaft'46 at right angles to yshaft 43. The shaft 46 is also provided with a gear47, which meshes with a gear 48 loosely mounted on the ,main driving shaft 18 and adapted to be engaged by the clutch 19, in the operation of the machine.l

lSuitable 'cutting devices are provided for cutting ofll the wire sections in the present instance; but these` cutting devices are both alike 'and only one will be described.

Suitable shearing cutters 50`4 are ad-V justably mounted in the ends of two levers 51, which are loosely mounted, intermediate of their length, upon a shaft 52. The lower ends ofthe levers 51 are pivoted respectively to one end of two links 53, thel lother end of the ,links 53 being pivoted to one end of'a fo`rk 54 adjustably connected to a rod 55, to

' forma differential toggle. The lower end of the rod 55 is pivotally mounted on a disk 56, eccentric to a shaft 57, which is provided 'with a gear 58, which meshes with a gear 59 on the secondary shaft 46. .j

adi they cutting levers 51. vBy referring to Fig. 6 it will be seen that the cutting levers51 are in open position, but when it is desired to cut 0E one ofthe wire sections,.the cutting levers51 are operated through the medium of the secondary shaft 46,' which operates twisted into two different vertical planes,

and as the forward and backward positions of the wire coiling devlce alternately presents thewire to the cutters in two different planes, it is necessary for the cutting devices` to cut thewire as it is presented in either position. vvItis for this reason that the levers 51 arepivoted to the shaft 52, which permits ofthe cutters operating to cut the wire whenit is presented in either plane, as shown in the right and left hand cutting devices shown in F ig. 6. It will be seen from`the above that when the cutting levers 51"are forced together one of the cutters 50 will come in contact with the wire, to be cut, before the other; but due to the pivoting of the cutting levers 51 and the flexir bility of the toggle the cutting levers 51 will automatically adjust themselves t0 operate the cutters to cut the wire in whatever polsition it is presented.

`The clutchl 19 (Figs. 1, 2, 4 and 5) is arranged to engage the gear 48 so as to turn the secondary shaft 46, to which the gear 47 is secured, one complete revolution, the clutch being forced out of engagement with the gear 48 at the end of one revolution of the shaft 46, by means of an arm 60 loosely mountedbn the hub of the gear 47. The gear 47 is provided with a projection 61 which in the single rotation of the gear 47 engages the side of the arm 60 raising'the same until the cam 62, on the arm,.engages the projecting roller 63 on the lever, 64

which operates the clutch 19 to disengage the gear48, the shaft 46 having been turned one complete revolution.V The clutch 19 is provided with a projection 65 which is adapted to engage the end of the arm 60 Vas soon as the cam 62 has forced the clutch 19 out of engagement with the gear 48, so as to force .the cam 62 entirel past the roller .63 to move the clutch 19 Into engagement `with the gear 17, whereupon the varm '60 drops by its own weight to the position shown in Figs. 4 and 5. .v y

When the clutch 19 isy in the position shown in Fig. 4, "power is transmitted from Athe main shaft 18 vto the wire coiling blade 13', through the medium of the gear 17 which meshes with a gear 16 secured to `the shaft 14 to one end of which the coiljust described, draws the wire from the reel 3 and forces it throughV vthe die 12, thereby t. lforming one wire lsection of the netting.

Acoiling. blade 13, the clutch .is for-eed into:v engagement with the gear 48 so asto rotate' the secondary shaft 46,0ne complete 'revolution,A at the end of which the arm 60 dis-l.'v

engages the clutch19 forcing the same ,into

- o erates to move ythe wire coiling device engagement with the gear 17 as before l,de-l

scribed.

In' the single rotation of the secondary' shaft 46, as just described, the ,eccentric 56. is operated to cut 0H" the wire section, lthe cam-42 rotating, on the idle portionof its cam groove, until `the/cutting device has operated to cut o the wiresection previously formed, after which the working portion of thel cam groove inl the cam 42 either. forward or backward as above described. In the present instance the camv 12 turns only .one-half a revolution for a complete cycle of operations, or for one revolution of the shaft 46, it being noted that in one cycle of operation the camf42'operates -end of the arm 82 isprovided with a roller to move the wire coiling device forward,

and in the subsequent cycle of operation. operates to move the wire coiling device-v backward.

` Fromthe above be seen that when' the clutch 19 is shifted to the right,h as

shown in Fig. 4, the -clutchiis in positionfor operating the wire coiling blade 13 to pro'- duce any desired length of wire section.- When the wire section has been made of ther desired length, the clutch19 is shifted to the" left to operate first, the wireV cutting device, and then the shifting of the wire coiling device, after which the clutch 19 is againshifted tothe right, asshown inv Fig. 4:,.and as before described to, again operate the.. ire coiling blade 13to produce a new lengt of wire section.

In addition to automjati'c'zallyV shiftingthe clutch 19 to the right by means'of the arm 60, after the wire cutting device has been operated, and the wire coiling device shift-v after the same has turned a certain number.

ed, as before described, automatic means are also providedfor disenga'ging the clutch l19. yfrom engagement with the gear 17 to stop the operation of the wire coiling vblade 13,

of revolutions to produce a lcertainlength of wire section, the clutch being .fo ced tothe left'to again. operate the wire cutt' gl devlce,

. and shift the wire coiling device. v Y

The clutch 19, as before described, is' engaged by the forked end of va lever 64: by means 'of pins 66, vthe lower end of rthe lever 64 being secured to the shaft '67 to which is alsol secured alever 68 provided, at oneside of its outer end, with va notched projection` 69.` l The notched projectionv 69 on the end of', the lever v68 is adapted to engage the lower end of a lever 70 which is pivoted at 71. j From the above it will be seen thatwhen the lupper end ofthe lever 7 Ois moved to the right 'I end of which is --s'ecured to the frame of the f machine, and the other end to one 'end of a short lever 73 lsecured to the shaft 67. This Y.

lever 64,' also secured to the shaft 67, to 1 upward movement of the lever 68 moves the "shift theclutch 19 into engagement with the l gearv 48.-

The clutch 1911s' automatically shifted-out of engagement with the gear 17 into engagementwiththe gear 48 byA means of an automatie timing device which operates the end of the lever 70. 4 v The timing device (see Figs. 4, 5 and 19) in the present instance vcomprises a vratchet wheel 8O loosely mounted onthel stud 81 secured tothe frame. arm 82 isalso loosely mounted \upon the stud .81, and -1s teeth 'of the ratchet Wheel 80. The upper- A84 .which engages the cam disk 85secu`red to one of thecoiling blade shafts 14; the rollerv 84j'being kept in-'contaetwith the cam '.85l by means ofaspring 86, one yend of which is secured tothe arm 82 and the other end provided with -a pawl 83 which engages vthe vto thefr-ame. The cam disk 85 is arranged to operate the arm k82 at the'- end of cach -coin'plete revolution of the coiling blade 13, 'thereby moving the pawl 83 to advance the ratchet iwheel 80 one tooth. The ratchet 'wheel "8.0 is advanced, tooth by tooth,for every complete rotation ofl the coiling :blade 13, and until the nosev 8T, secured to the ratchetv wheel 80, comesin contact with the end of the lever 70 to move the same, @thereby disengaging the other end of the lever 70 fromjthe notched projection 69 on the lever 68,.60 operate the clutch 19 as .before described. Asthe ratchet wheel' 80 is advanced bythe movement of thepawl 83 .the ratchet wheel is held in advanced position by means of a spring -pressedpawl 88 secured to he frame. t

When the ratchet wheel '80 has been ad- "vanced far enough .for the nose 87 to trip thelever' 70, .to release the lever 68, so as to operate the clutch 19, the upward movee end-of the bar`90 to move the sameupward. The -bar 90 is provided with pins 91 "ent of the lever 68 engages the' pin `89 on i', 125

and92` which respectively engage the pawls 88 and 83 to move the same out' of engage' l ment with the ratchet wheel 80. v. As soon the pins and 92 move the pawls 88 and 83 out of engagement with the ratchet wheel 80, the ratchet wheel is moved back to its starting position by` means of a flexible cord 93, one end of which is wound about the hub of theV ratchet wheel 80, the other.

end of the cord 93 being secured to one arm of a bell-crank lever 94 pivoted to the shaft 67, the other arm of the bell-crank lever bej ing secured to one end of a'spring 95 secured to the frame 9.l j

lThe ratchet wheel 80 is moved backward after tripping the lever 70, as just described,

until-an abutment 96,* on the front of thev hub of the ratchet wheel 80, comes in contact with a shoulder on the back of a setting arm 97. The ratchet wheel 80 remains'in this position until the clutch 19 is again operated to turn the wire coiling blade, at which time the'lever 68 is depressed so as 2o to permit the bar 90 to drop the pawls 88 the abutment 96 on the hub of the ratchet I wheel 80, when the ratchet wheel' 80 is moved to its starting position by means of the exiblecord 93 as before described. The setting arm 97 is provided with atoothed screw bolt 100) which is adapted to engage the toothed periphery of a timing disk 101,

40 keyed to the end of the'stud 81. The timing disk -101 is provided with the 'same number of teeth as the ratchet wheel 80. It is to be noted that the nose 87, which trips the lever 70, is secured to the ratchet wheel 80 on a 4,5J radial line with lthe workingedge of the abutment 96, on the ratchet wheel 80, and` it is also to be noted that the shoulder 99 on the setting arm 97 is in line with the toothed screw bolt 100; so that when the ratchet wheel 80 is moved to its starting positionthe'nose 87 will be in radial lalinement with the toothl on the timing disk engaged by the toothed screw bolt 100 on the setting arm 97.

The setting arm 97 being loose on the stud 19, the same can be set at any desired position about the timing disk 101 so as to bring the shoulder 99 on the settin in line with any desired'tooth on the timing disk, the teeth of which are preferably numbered beginning with the tooth on the time isk which is opposite the end of the lever when the same is tripped by the nose 87 on the, ratchet wheel v80. The number of arm f teeth on the ratchet wheel are the same 65 vas the number of teeth on the timing disk 101, the ratchet wheelbeing advanced one tooth for every revolution of the coiling blade 13, so if it is desired to produce a certain length of wire section represented, 70 for example, by forty-five revolutions of the coiling blade 13, the setting arm 97 is set asl/shown `in Fig. 4,'opposite the tooth numbered 45.

When the setting arm 97 has` been set op- 75 posite the number 45 on the timing disk, it will be seen that the abutment 96 on the ratchet wheel 80, will engage the shoulder 99 on the back of the setting arm 97 so that it -will take lforty-five revolutions of the 80 j coiling blade 13 to advance the ratchet wheel tooth by tooth, for the nose 87 on the ratchet wheel 80, to trip' the lever 70,l to shift'the clutch 19 to stop the wire coiling blade. After the lever 70 has been 85 tripped by the nose 87 and the clutch 19 operated, as just described', it ywill be seen that the upward movement of the lever 68 raises the bar 90 thereby disengaging the pawls 88 and 83 from the ratchet wheel 8090 so as to permit the spring 95, through the L medium of a flexible cord 93, to vturn the ratchet wheel back to its starting position. When the clutch 19 is shifted again into engagement with the gear 17 the lever 68 is 95 lowered permitting the pawls 88 and 83 to fagain engage the ratchet wheel.

If it is desired to produce a greater or less length of wirev section thanv is'produced when the setting arm 97 is set for forty-five 100 revolutions of the coiling' blade 13, as shown in Fig. 4, the. bar 90 can be raised by hand to release thev pawls 88 and 83, so as to release the ratchet wheel which can be moved to a new starting position by the movement of the` setting arm 97 to the number on `the timing disk representing the desired number of revolutions of the coiling blade.

As' each length of wire section is finished and cut ofi", the wire coiling device is shifted so that the new length of wire section will intermesh with the previously formed wire section, as previously described. This shifting of the wire coiling device either forward or backward a distance equal to one-half the pitch ofthe coils of the wire, every time a newv length'of wire sectionhis added to the netting would make the wire sections ofdi'erent lengths, provided the timing devicev always gave the same num- 120 ber of revolutions to the coiling blade 13. In order to overcomethis difficulty theV timing device is arranged to give one more revolution to the coiling blade 13 every time the coiling device is shifted backward, the

y coiling blade 13 therefore being given one less` revelation every time the coiling device lis shifted forward.

v I, ln order to give one more revolution to l 4 vided a link 102 the coilingl blade 13 everyl time the .coiling device is shifted backward, there 1s proarm 40, secured to the rock'shaft-39, which is rocked by the lever 38, 'through the medium of the cam42. The arm 40 -is pivf' oted'to the end ofthe link 102 by means of 1 ing disk 101 to be moved forward or back. ward one tooth.` From the above it will be seenf that when the wire coiling device is,

a pin 103 which is adapted to engage a slot 104 in the end of the link 102, so thatwhen the arm 40 is moved towardtheleft, in the forward movement of the coiling device, itv

' will operate the link 102, but when the arm 40l is moved to the right, in the backward movement of the coiling device the pin 103 in the arm 40 will not engage the link102 moved forward the arm 40 will pull the link 102to theA left to turn the timing` disk 27 one vtooth forward, thereby forcing the shoulder 99 on the setting larm 97, which is securedfto the timing disk 101, to turn the ratchet wheel 80 forward onetooth. When -the arm 40, is moved tothe right, in the backward movement of the coiling device, lthe link 102 is" released, therebyl permitting the abutment-96, -on the ratchetfwheel 80,

` which 4engages the shoulder 99 on the setting c arm 9.7 secured to the timing disk 101, to turn the timing disk backward one tooth by the action of the flexible cord 93.

lWhen the timing disk is in the position shown in Fig. 4 it .is in the normal start.

ing position, in which position the wire coiling device is in its forward position, the y timing disk being held in this position Jthrough the medium of thelink 102 so thatthe coiling vblade 13 will be stopped in the operation ofthe machinet'the end Jof fortyf ve revolutions, for which the arm.197 has beenset. When the coiling blade has been revolved forty-five revolutions to produce a certain length of wire section and the'wire cut ofi", the wire coiling device in the further operation of vthe machine will be moved backward, thereby permitting the. timing disk to turn backward one tooth as before described. When the'timing disk is moved backward one tooth the startlng point of the t nose' 87 is thereby set back one tooth, so that the nose 87 will not trip the lever 70 until the coiling blade 13 has made forty-six revo- ``l1\1tions,f to-produce a'length of wire section that is one coil longer than the previously formed wlire section which was made when the coiling-device was in its forward posiv pivoted at one end to. the timing disk 101', andatthe other endv to the.`

tion.' From the above it'will be seen that when the wire coiling .device is in lts forwar'd position the timing device-is arranged vto control the 1 timing of vthe coiling blade,

to produce a wire section thathas .one coil less than when-the wire coiling device is in its backward position. l

- Asjbefore stated the wire coiling device ismoved forward or backward a distance equalto one half the lengthof one of the coilsof the wire, every time a new length of twisted wire section is to be added to the netting, so .as to permit of the new length of twisted wire section its forward movement, to` intermesh with the 1 previously formed wiresection. The shift-A ing of the coiling'device either forward or backward a distance equal to one-half the length of one of the coils, to the vpositionv shown in Fig. 23, so that when the wire section B is formed its coils` `Will 'intermesh with the coi-ls of the wire section A, the wire shown in Fig. 24` -After vthewire section B has been cut oif thewire coiling device is again moved forward aV'distance equal to one half the length of wire of thev coils, to the position shown in Fig. 24, so that when the wire section C is formed its coils will intermesh with the coils of the wire sectionB.-

In order to -make all of the different wire sections of equal length, so as to compensate for the forward and backward movement of the coiling device, required to interweave the different wire'sections, it is necessary to add one more coil to the wire sections produced when the coiling device isl inits backward position. By referring-tb. Fig. 23

,l it will vbe seen that the new section B will have to 'have five complete coils to reach Ahas-been shifted, by the coiling device',.after the wire section'A'has been cut oli'. By referring to Fig. 24 it will be seen that the new section C. willhave to have four comf plete coils'to reach the left-hand end of the previously made sections A and B, the startling point of the section C being one-half coil infront of the cutting line :v /.v to

.section B being cut o onl the line as which position the end of the wire has been shifted, by the ceiling device, after the wire 'section B hasbeen cutoff. From the above above described, and as shown in Fig. 7, the

twisted wire in its forward movement being held in position and guided by means of a tubular-guide 107, (Figs. 1 and 3) which is open at the top throughout its entire l length as shown in Fig. 8. As the machine is built as a doublemachine two guides 107 are provided but as both guides are alike only one kwill be described. The guide 107 is supported upon the cross channels 108 and y109, the ends of which are mounted upon two longitudinal channels 110 andv 111 secured to fai-H1115. 4

The interweaving or intermeshing of the wire sections, as above described, forms the netting which passes over suitable rollers 116 mounted upon the shaft 117 secured to the frame vchannels 118. vThe rollers 116 the uprights 112, 113, 114

are preferably supported so that the netting will hang in a vertical plane over the Slot in the interweaving guide 107 asf shown in Fig. 8. The netting is wound upon a takeup roller 119 removably supported on the frame, the roller 119 being provided with detachable flanges which can be detached when it is desired to remove the netting from the roller. The roller 119 is turned to wind up the netting asit isl made by `means of an arm 120 one end of which is provided with a plurality of pivoted gripping lingers 121the movements of which are regulated by means of pins 122. rIfhe other end of the arm 120 is blfurcated and embraces the sec- .ondary shaft 46, the arm being provided with a roller 123 which engages a cam 124 on the shaft 46. A spring 125, one end of which is secured to the arm 120 and the other end to the shaft 46, is providedfor keeping the roller 123 in engagement with the cam 124. As the secondary shaft 46 is rotated, in ythe operation of the machine, the arm 120 will be moved longitudinally back and forth, by the action of the cam 124, the gripping fingers' 121 engaging the\periphery of thel netting roll to wind the same upon the roller 119. A plurality of gripping fingers 121 are provided to insure at least one of the gripping lingers engaging theperiphery of the netting roll. The cam 124 netting roll, so that; the netting roll will all ways be advanced a distance equal to the width of one wire section regardless of the diameter of` the netting roll'.

As the machine is a double machine two arms 120 are operated by the same cam 124,

otherwise the means for Winding the netting are duplicated. l

lTo insure the netting being lifted the proper distance at the proper time wire lifting devices are provided, which are, in the present instance, situated just above the tubular guides 107.

' As the machine is a double machine and as t-wo simi/lar lifting devices are providedy for each lnetting only one lifting device will be described.`

The lifting device inthe present instancev 134 and 135, as shown in Figs.- 3 and 8.

, The sprocket Awheels 130 and -131 are spaced apart a distance equal to one-half the itch ofthe coils of the wire as shown in Figs. 3 and 20. The teeth on the sprocket wheels 130 and 131 are both alike, the wheels being set on the shaft 132 'so that the teeth on both wheels are arranged alternately with respect-to each other, as shown in Figs. 8 and 21. The teeth on the sprocket wheels 130 and 131 are arranged to engage the joints of the netting, the teeth of both wheels being adapted to always engage the netting at three joints, one tooth of one sprocket wheel engaging the netting at one joint,

while two teeth of the other sprocket wheel engage the netting. at two j oints', and when, in the operation of the machine, thes rocket Fwheels are turned to liftl the nettlng the.

first-named sprocketwheel engages the netting at two joints and the last-named sprocket wheel engages the netting at one j joint, and so on, Yas shown in-Figs. 8, 20 and 21. .l

To insure the engagement of the teeth of thev sprocket wheels 130 and '131 with the joints of the netting, as vabove described, suitable guides 136 are provided for holding the netting. The guides 136 are, in the present instance, situated between the sprocket wheels 130 and 131, and are secured at their ripper ends to the cross pieces 137 mounted on the frame.-

The sprocket wheels 130 and 131 are" turned, in the operation of the machine, to lift the netting, through the medium of a during ratchet wheel 138 isy advanced one tooth to thereby advance the sprocket wheels vone.- -half tooth, to `lift the netting a distance ratchet wheel 138 secured to the shaft 132 between the sprocket wheels. The ratchet wheel 138 is arranged to be operated by meansiof a spring-pressed pawl 139,piv

yoted to one end of a bar 140 slidably mount-- ed -in brackets 141. VThe lower end of the bar 140 is slidably secured to one'end of a lever 142 which is pivoted at its other end to the frame. The lever 142 is pivotally connected to one end of a link 143, the lower end of which is slotted to embrace the secondary shaft 46upon which is mounted a cam 144 arranged to engage two rollers 145 on the link 143.

The teeth on the ratchet wheel 138 are equal to the sum of the teeth on the sprocket wheels 130and 131, so that when the pawl 139 is operated, as before described to advancevthe ratchet wheel 138 one tooth,.the sprocket wheels 1,30 and 131 will be advanced only half. a tooth, so as to lift the netting a distance equal to the width of one wire section. By referenec to Figs. 8, 20 and 21, it will be seeny thatA the sprocket wheel 130'v engages 'only one joint of'dthe netting, whereas the sprocketfwheel 131 engages two joints of the netting, but when,

equal to the width of one wire section, the sprocket wheel 130 will engage the netting at two joints and thev sprocket wheel 131 will engage the netting at one joint.

In order to lock the sprocket wheels 130 and 131 in position after they have been moved to lift. the netting, locking hooks 146 are provided which are pivoted at one end to the frame, the other end being arranged to engage -the teeth of the sprocket wheel.

' The hooks 146 are operated to release the sprockets by means of a pin 147 which extends on opposite sides of the bar 140 to which it .is secured. The hooks 146 are each provided with a pivoted lug 148 which y lugs are adapted to be engaged by th'eends ofthe pin 147 when the rod 140 is moved downward to advance the sprocket wheels. When the ends of the pin 147 engage the lugs 148 on the downward" movement of the rod140, to release the hooks from engagement with the .sprocket wheels, the lugs 148 are so arranged, in relation to thefendsof the pin 147, that the ends of the pin will move. past the lugs on the hooks to permit the hooks to move back again into engagement withthe lsprocket wheels'by the action of the springs 149 attached to the hooks, the r pawl 139, on the rod 140 havin advanced the ratchet Wheel 138.one toot 'As the4 teeth on the sprocket wheels 130 and 131 are in -alternate relation with each other, only one lof the hooks 146 engages one of the the operation of the machine, the

each netting are provided lwith a selvage gripping fingers sprocket wheels at a time to hold the sprocket Y Awheels in locked position.

l The lifting'device, as aboveidescribed, is arranged to be operatedv through the medium of the secondary shaft 46, to lift the netting a distance equal to the width of one wire section, just after the wire coiling device has inished coiling a new wire section, and just previous to the time the cutting device 'is 4operated to cut 0E the new wire section, so that the -new wire section will be suitably held in the tubular guide 107, to allow. another wire section to be interwoven therewith. By referring to Fig. 23 it will be seen that when the wire section marked B has been twisted to the desired length, as shownrin dotted lines, the previously formed wire sectionmarked A will be lifted to the position shown in Fig. 24 to thereby support the wire section mar-ked B in position to permit of the wire section C being interwoven with the wire section wire, four selvage wire devices are provided; and as all the selvage wire devices are alike only one will be described.

The selvage wire device (see Figs. 9*-18 inclusive) in the resent instance comprises 50 the engaging ends-of which are notched, as shown in Fig. 14,-so as to hold the joint formed by two wire sections, at the sides of the netting, t ogether with the selvage vwire Z, firmly in place. The gripping fingers 150 are pivoted to the sides of the casing 151, andare arranged to be operated by one end of the adjustable cam blocks 152, the other ends of which are provided with rollers 153 which are adapted to 'engage the camrned periphery of the cam disk 161 against which the rollers 153 areheld by means of the springs 154. The rear ends of the gripping fingers' 150 are kept in contact with the cam blocks 152 by means of a U-shaped,

spring 155 placed between the forward ends of the gripping fingers. .The selvage wire Adevice also comprises in the present into engage suitable cam grooves in the sides of the cam disks 160, 161, 162,3.150 munted vin the casing 151y upon the shaft 163. The

shaft 1634 is operatively connected to the spiral gear 164 which meshes With a splral 'gear 165, mountedon a shaft 166, which is operated by the secondary shaft 46,;` by means of the Sprocket Wheels 200 and 201 and the chain 202.

`The selvage Wire device, as above described, is arranged to be operated, through the medium of the secondary shaft 46, to attach the selvage Wire Zto the side of the netting, just after the lifting device has operated to lift the netting a distance equal to the Width of one Wire section. After the netting has been lifted, as above described, the cam disk 161 operates to close the gripping fingers 150 so as to hold the joint formed by tWo Wire sections together With the selvage Wire Z. The gripping fingers of the 'Wire selvage device are preferably arranged to grip and hold the joint' at the side of the netting that is in line with the kjoint which is held in place between the two teeth of the sprocket Wheel of the liftingdevice, which supports the netting atone joint as before described.

When the gripping lingers have gripped the joint and selvage Wire as above described, and as shown in dotted lines in Fig. 14, the cams 160 and 162 operate to move the tools 156, and 158 into engagement With the loose ends of the Wiresections of the joint held by the `gripping fingers to bend the saine into the position shown in Figs. 15

vand 16. When the tools 156 and 158 have "move the tools 157 and 159 into engage-A ment with the partially bent ends of 'the Wire sections, to bend the same about the selvage Wire Z, as shown in Figs. 17 and 18. When the loose end ofthe Wire sections have been'bent about the selvage Wire to securely fasten it to a joint at the side of the netting the. further movement of the cams operates to Withdraw the tools and open the gripping lingers.

he selvage Wire Z comes 'from an independent sourc'e and is guided through suitable eyelets 167 yover a suitable roller 168 secured to the Wire selvage device as shown in Fig. 9.

After the selvage Wire device has nished attaching the selvage Wire to one joint, as above described, the netting, in the operation of the machine, Will be lifted a dis-` Width of a vvire section, when the Wire selvage device will engage another joint to 65 attach the selvage Wire. r The operation of the machine isy 'as follows:

f The Wire for making the netting is first Wound upon the reels 3, and theends of the Wire led to the two separate Wire' coiling devices 11, so as to make tvvo independent nettings.- The setting arm 97 is thenv adjusted on the timing disk to control the length of the Wire sections to produce a certain Width of netting, the arts being in the position shown in Fig. 4. he main shaft 18 is then started With the clutch `19 in engagement with the gear 17 to operate the coiling blades 13 of both Wire coiling devices. .When 580 the Wire coiling blades have made the predetermined lengths ofA Wire sections,'.the timing device operates to shift the clutch 19 into engagement with theN gear 48. The shifting of the clutch 19 by the operation 85 of the timing device, stops both Wire coiling devices and forces the clutch into engagement with the gear 48 to turn the secondary shaft 46 one complete revolution.

One complete revolution of the secondary shaft 46 operates first, the Wire lifting dethrough the` gears 58 and 59'; third, the self vage Wire devices for each netting, through the medium of the spiral' gears 164 which 10 0 mesh with a spiral gear 165 on the shaft 166 operatedby the' secondary shaft 46 by means of the sprocket chain 202; fourth, the Wire coiling devices by vmeans of the `cams 42 mounted on the shaft 43 connected to the 105 secondary Shaft 46 by means of the spiral gears 44 and 45; fifth, the take-up by means of the cam 124 mounted on the secondary shaft 46 through the medium of the arms sixth, the arm 60 mounted on the sec` 110 Qndaryshaft 46 through the medium of the p1n 61 to stop the secondary shaft 46 at the end of onev revolution, the projection 65 on f the clutch 19 engaging the end ,of the arm 60 to force the clutch 19 again into engage- 115 ment With the gear 17, all ofthe operating parts having assumed their normal position. If desired the Wire oiling devices can be arranged to make nettlngs ofdiiferent Wire mesh, and it isobvious that one Wirel coiling 120 device can be arranged to produce one size netting, While the other wire coiling' device 1s arranged tolproduce a' different size nettlng, at one and the same time, the different parts of the machine al1 working together.

It is also obvious that the machine can be
